    • The invention relates to a method in signal processing for quantizing likelihood quotients of binary random variables for transmitting between at least two signal processing units. Decision levels and reconstruction levels of a quantization of likelihood quotients are thereby determined by maximizing (10) corresponding information between the binary random variables and the associated quantized likelihood quotients at a prescribed probability distribution of the likelihood quotients. The invention further relates to a corresponding quantization device. For the quantization device, means are provided for determining decision levels and reconstruction levels of a quantization of the likelihood quotients by maximizing the corresponding information between the binary variables and the associated quantized likelihood quotients at a prescribed probability density of the likelihood quotients.
    • 本发明涉及一种信号处理方法,用于量化二元随机变量的似然变量以在两个或更多个信号处理单元之间传输。 通过最大化(10)二进制随机变量与相关量化似然商之间的互信息来确定似然商的量化的决策水平和重构水平,用于给定概率分布的似然商。 此外,本发明涉及相应的量化装置。 对于量化装置,用于确定判定级别和似然比的量化的重建水平通过最大化二元变量和相关联的量化的似然比之间的互信息的似然比的一个给定概率密度设置。
